- Abstract
Studying life and physical sciences under reduced gravity is crucial because microgravity environments expose phenomena that are obscured by Earth’s gravity. In space, the absence of buoyancy and sedimentation allows us to observe fundamental processes in ways that drive breakthrough innovations—advancements that are directly applicable to both space exploration and terrestrial technology. Combustion experiments conducted on orbital platforms such as the International Space Station (ISS) have revealed unprecedented details of the burning process. In microgravity, flame structures and soot formation behave differently, enabling researchers to isolate chemical kinetics from convective effects. These insights are key to improving the efficiency of combustion engines and reducing environmental loads from power plants on Earth. For instance, experiments using the Combustion Integrated Rack (CIR) have provided data that are helping to refine models of flame propagation and pollutant formation. Life Support Systems Development: Research in microgravity is also revolutionizing the development of life support systems for spacecraft. Experiments on the ISS and on Chinese and commercial platforms are advancing technologies for waste treatment, rapid detection of microorganisms, and space-based food production. These systems not only ensure the health and safety of astronauts on long-duration missions but also foster innovations with potential applications in sustainable agriculture and environmental management on Earth. Looking forward, upcoming platforms such as NASA’s Deep Space Gateway and commercial stations like Orbital Reef will expand our capacity to conduct microgravity experiments. This research will further optimize closed-loop life support systems and enhance our understanding of materials processing and fluid dynamics in space. By combining results from combustion studies and life support experiments, our research under reduced gravity is paving the way for improved engine designs, environmentally friendly technologies, and sustainable living systems—innovations that are essential for the future of space exploration and have significant benefits on Earth.
